據個人嘗試 以下這種方案能準確監聽到是否滾動到底部，可以做上拉載入更多

protected boolean isSlideToBottom(RecyclerView recyclerView) {  
    if (recyclerView == null) return false;  
    if (recyclerView.computeVerticalScrollExtent() + recyclerView.computeVerticalScrollOffset() >= recyclerView.computeVerticalScrollRange())  
        return true;  
    return false;  
}  
 

recyclerview.addOnScrollListener(new RecyclerView.OnScrollListener() {  
           @Override  
           public void onScrollStateChanged(RecyclerView recyclerView, int newState) {  
               super.onScrollStateChanged(recyclerView, newState);  
           }  
  
           @Override  
           public void onScrolled(RecyclerView recyclerView, int dx, int dy) {  
               super.onScrolled(recyclerView, dx, dy);  
               LogUtils.d("------->isSlideToBottom:" + isSlideToBottom(recyclerView));  
               if (isSlideToBottom(recyclerView)) {  
                   srlLayout.setEnabled(true);  
               }  
           }  
       });
